.12 of the holder 7 through the medium of cured to the gear also of conductive maradiating bars 13 terial, and so that rent passing through the goods contained in the holder will pass through the frame members 11 and 12, through the arms 13 and thence through gear 7 and gear 6 meshto the shaft 2 to complete the ing therewith electrical circuit as hereinafter described.

A section 14 of the peripheral wall ot the body 10 is slidably mounted in order to constitute a door for gaining access to the interior of said body. the lateral edges of the section 1i heilig in dmetai'l connection with the adjacent edges of said body, the frame member 11 at one side being cut away as at 15 in order to afford clearance forsaid section as will be readily understood. The door section 14 is releasably secured in closed position through the medium of a suitable locking device 16. lheinwardly extending flanges of the frame member 11, at the opening which is formed upon removal of the door 14 are cut ,away as clearly shown in Fig. Q so as to not' obstruct said opening.

Arranged in the tank 1adjacent the up )er edge thereof and at either side of the holder or container are bars 17 from which depend' anode-forming electrodes v18. Upon bearing 3 and corresponding extremities of the barsr 17 are binding posts 19 ind- 20 respectively ,torlconnecting the sameo'vith a source of The circuit which is thus formed includes the-frame members 11 and or container which form cathodes and theA electrodes 18 which constitute anodes, said electrodes being electrically connected in order to close the circuit by the electrolyte the tank 1 in the electroplating process and the articles arranged in holder for plating.

ln operating' the device, the articles which it is desired to plate are first introduced into the holder or container body 101through the door 14. It it is desired to clean the articles before electroplating, a cleansing liquid is introduced into the tank 1 and the containe revolved'vtherein through operation of the shaft After cleansing and rinsing of thc articles,thc container is placed in. another tank 1 in which an electrolyte isprovided or if desired the same will be per; mitted to remain in the'tank 1 from which the cleansing liquid has been removed and into which the electrolyte has been introduced. The 4container is then rotated as before in the electrolyte. lV hen this is done it will be seen that the articles resting in contact Ywith the rame members 11 and 12 of the container body will become the cathodeV in use the electrical eurl which is introduced into through the electrolyte from the f been plated the container may be removed from the tank 1 by disengaging the gear 7 i from the gear 6, such disengagement lseing readily effected since the gear 7vsimply rests i upon the gear 6 as above described. l the coat or plating has dried upon the articles, the container may be rotated as before l in the empty tank l in order to eiectbu- ,i nishing or polishing thereof it being clellr 1 upon rotation of such container the articles l will rub against cach other and thereby poll ish the same as desired. l Alt is thus seen .that with the construction set forth, the entire electroplating process l may he carried on l removal of the articles treated from thel container in which the same are arranged rat the commencement of the treatment, the articles being removed from -said container only upon completion of the electroplating. This is fendered possible by reason of the detachable-arrangement of the container in the l tank, said container, wherea plurality of tanks'are used in the process, being simply removed from one tank and placed in another as will he neadilynnderstood. Ful ther with this construction the loss of elec-4 trical energy isobviatcd since with this con- I struction, the circuit is closed upon thc insertion of the. container in the tank or when gear 7 contacts with the gear 6 .and broken when said container is removed from the tank or when the gear 7 is disengaged from the gear 6, the circuit being thus closed only when the container is in operative position. l Also with this construction the necessity of a hand operable switch is 'dispensed with l since the breaking and closing of the circuit 1is automatically effected upon removal or insertion of the container in the tank.

Numerous other advantages of the Aconstruction which it is not necessary here to mention will be apparent to those skilled in the art. "A

In Figs. from 8 to 10, inclusive, is shown l a construction which is a. slightmodiiicm ltion of that just described. In this conlstruetion the container 10 is longer than I that ot' the preferred form and at each end l of said container is provided a gear`7 and t the partswhich .cooperate therewith to which the respectivel ends of said container l are connected in the same manner as the gear 7 is connected with'the container body 10 in the preferred form. The gears 7 of the modified form mesh'with gears 21 which are provided at' th'respectlve' ends of a shaftc22lwhich s mounted inv suitable bearings 23 provided i1` 4 cr a'ss pieces '24 which rest' loose1y uponf supper edges of opposing Walls o'ftheftank. he4 arrangement 1s Such as will 'be 'observed that upon rotation of the shaft QZIth'e container 10 depending therefrom will-:be rotated in the same manner as the container 10 of the preferred After iid @ammo funn.l The removal of the conmner in ih@ modlfled form however is eectcfl by enga@ ingA the opposite ends' of ille cross places *2,4 g
